Availability Testing for API Gateway Failover Mechanisms

What is API Gateway Failover Availability Testing?

API Gateway Failover Availability Testing ensures that your API gateways can handle traffic rerouting effectively during outages or disruptions. This template utilizes LoadFocus Load Testing Service (LoadFocus) to simulate thousands of concurrent users from over 26 global cloud regions, validating your gateway’s reliability and responsiveness under failover scenarios.

Designed specifically for API gateways, this template helps identify gaps in failover mechanisms and ensures that disruptions don’t impact end-user experiences.

How Does This Template Help?

This template provides structured steps to simulate failover scenarios, measure performance metrics, and validate API gateway reliability during disruptions.

Why Do We Need API Gateway Failover Testing?

API gateways are critical for routing and managing traffic in distributed systems. Failures in these components can lead to downtime, degraded performance, or data loss. This template ensures your gateways can manage failover scenarios effectively, maintaining availability and user satisfaction.

• Validate Traffic Rerouting: Ensure seamless rerouting of traffic during disruptions.
• Identify Performance Gaps: Detect latency or bottlenecks during failover.
• Maintain User Trust: Demonstrate reliability and minimize downtime during critical events.
